IC薛苗 (,214200) 在(35±1)℃温度条件下,对内循环厌氧反应器(IC反应器)处理啤酒废水的启动特性进行了研究。结果表明,IC反应器经过56d启动成功,其容积负荷达到18.3kg/(m3·d),水力停留时间为3.2h,去除率能稳定在80%以上;随着反应器的运行,反应器内形成了大量的沉降性能良好的颗粒污泥,粒径0.5mm的污泥约占87%,颗粒污泥平均沉降速度达69.92m/h。 IC厌氧反应器;啤酒废水;颗粒污泥 TS262.5   A   0517-6611(2010)26-14816-03Start-upofICAnaerobicReactorTreatingBreweryWastewaterXUEMiao (YixingEnvironmentMonitoringStation,Yixing,Jiangsu214200)Abstract InvestigationoncharacteristicsofbrewerywastewaterbyICanaerobicreactorwascarriedoutundertheconditionof(35±1)℃.Theresultsshowedthatthestart-upofreactorwasfinishedafter56days.Andthevolumeloadingrateof18.3kg/(m3·d)andCODremovalrateofmorethan80%wereachieved.Thehydraulicretentiontimecouldbe3.2h.Furthermore,awealthofgranularsludgecameup,thenumberofmorethan0.5mmingranularsizewas87%andtheaveragevelocitycouldbe69.92m/h.Keywords ICanaerobicreactor;Brewerywastewater;Granularsludge 薛苗(1981-),男,江苏宜兴人,助理工程师,从事水污染控制工程研究。 2010-06-25  、、、[1]。,、,10~20m3/t[2]。、、、、、。。BOD/COD,,。,,、。[3-6]。ICEGSB(Expandedgranularsludgebed)、IC(Inter-nalcirculationanaerobicrector),,,,,。IC,IC。1 1.1  1。180cm,10cm,18,20L。2。1,,;2,,。,1,。,(35±1)℃。,1,,,。,。1.2  。COD2500mg/L,BOD15001 Fig.1 Diagramofanaerobicreactormg/L,B/C0.6,TN30~40mg/L,TP5~10mg/L,pH4.0~6.0。1.3  。,,(MLVSS)(MLSS)0.62,7.69g/L。,10L,1/2。1.4  [7]COD;[7](SS);[7](VSS);[7](VFA);Orion828pH;[8];[8]。,30min,105℃,。2 2.1 COD 、3。NaHCO3pH7~8,,ICpH,NaHCO3pH。,COD,5kg/(m3·d), 刘月娟  卢瑶,JournalofAnhuiAgri.Sci.2010,38(26):14816-14818(HRT)12h,2COD80%,。2,COD2 Fig.2 Influent/effluentCODconcentrationsduringoperation,3dCOD70%,8d,COD80%,“”“”。30L/d150L/d,16.0h3.2h,1~2dCOD,1~2d,80%。,。351,2,,。。5618.3kg/(m3·d),COD85.8%,,COD,SS,VFA。,18.3kg/(m3·d)。,30d,,COD,VFA,,。2.2 COD IC,10、20、30、40、506012COD。1,,COD95.6%。,,,,2,1。、,1COD95.6%71.4%,。,,;,,,,,12,COD。1COD2,IC1。1,COD。1 CODTable1 CODconcentrationindifferentreactionzone∥dTimeCOD∥mg/LInfluentCOD1COD∥mgLEffluentCODoffirstreactionroom2COD∥mg/LEffluentCODofsecondreactionroom1COD∥%ProportionofCODremovalquantityoffirstreactionroom∥%Totalremovalrate101886.082.9298.095.684.2201656.0124.2435.692.579.7302284.7351.8383.084.683.3401897.6392.8348.079.381.7502424.7560.1298.476.987.7602394.8684.9467.071.480.52.3 pHVFA ,pH6,IC,,VFA,,,,。,VFA,。2pH。NaHCO3pH7;pH,。,IC,pH,,pH[9]。COD,0.5~5.0[10]。pHVFA。3,VFA202~404mg/L。,VFA。,,;,,,VFA,,,VFA,VFA。pH,6.8~7.2,。pH。pHVFA。VFA,pH。,,VFA、。2.4  1481738卷26期                 薛苗 IC反应器处理啤酒废水的启动试验研究3 pHVFAFig.3 Relationshipofinfluent/effluentVFAandpHvalue[11]。。[12-14]。18~100m/h,20m/h[15]。4,59.6~93.0m/h,69.92m/h,;,2.0mm102.0m/h。4 Fig.4 Settlingvelocityofgranular  5,0.5mm28%,0.5~2.0mm,5 Fig.5 Sizedistributionofgranularsludgeafter55daysoperation67%;2mm,5%,,,。,IC,。3 (1)(35±1)℃,IC。56d,IC18.3kg/(m3·d),(COD、VFApH)。(2)1COD2,1。(3),VFA202~404m/L,,;,pH。,,VFA。(4),,59.6~93.0m/h,69.92m/h;2.0mm102.0m/h。,0.5~2.0mm67%。[1]王志坚,杨佳茹.啤酒废水处理技术[J].酿酒,2002,29(3):26-27.[2]吴速英,叶雪均,肖隆文,等.ABSBR处理啤酒废水的启动试验研究[J].工业安全与环保,2005,31(2):13-15.[3]王林山,吴允,张勇,等.生产性IC反应器处理啤酒废水启动研究[J].环境导报,1998(4):22-24.[4]MARIOTK,SALIHR,GATZEL.Anaerobictreatmentoflow-strengthbrewerywastewaterinexpandedgranularsludgebedreactor[J].AppliedBiochemistryandBiotechnology,1999,76:15-32.[5]SHAOXW,PENGDC,TENGZH,etal.Treatmentofbrewerywastewaterusinganaerobicsequencingbatchreactor[J].BioresourceTechnology,2008,99:3182-3186.[6]BALOCHMI,AKUNNAJC,COLLIERPJ.Theperformanceofaphaseseparatedgranularbedbioreactortreatingbrewerywastewater[J].Biore-sourceTechnology,2007,98:1849-1855.[7]国家环境保护总局,水和废水监测分析方法编委会.水和废水监测分析方法[S].4版.北京:中国环境科学出版社,2002.[8]陈坚.厌氧污泥颗粒化和UASB反应器放大的研究[D].无锡:无锡轻工大学,1990:33-35.[9]胡纪萃.试论内循环厌氧反应器[J].中国沼气,1998,17(2):3-6.[10]PEREBOOMJHF,VEREIJKENTLFM.Methanogenicgranuledevel-opmentinfullscaleinternalcirculationreactors[J].WatSciTech,1994,30(8):9-21.[11]任洪强,丁丽丽,陈坚,等.EGSB反应器中颗粒污泥床工作状况及污泥性质研究[J].环境科学研究,2001,14(3):33-36.[12]许英杰,冯贵颖,买文宁.生产性IC反应器厌氧颗粒污泥的生物学特征[J].环境污染治理技术与设备,2005,6(4):84-85.[13]COSTAJC,MOITAI,FERREIRAEC,etal.Morphologyandphysiologyofanaerobicgranularsludgeexposedtoanorganicsolvent[J].JournalofHazardousMaterials,2009,167:393-398.[14]BUIXT,CHETTIYAPPANV,ROGERBA.Characterizationofaerobicgranularsludgeatvariousorganicloadingrates[J].ProcessBiochemistry,2009,44:242-245.[15]王建龙.生物固定化技术与水污染控制[M].北京:科学出版社,2002:181-187.14818          安徽农业科学                         2010
